41 & 33 together usually means a vacuum leak in the EGR vacuum hose. Check it for cracks, etc. Otherwise, verify the hose is not blocked, and then apply 10" of vacuum w/ a vacuum pump to the EGR valve while the engine is idling. If the engine stalls, or stumbles, the system works. Next watch to see how well the EGR holds and maintains that 10" of vacuum.
Post your results. Take care, ~Chris
